If you’re buying fish from your local wet market, check the eyes, fins, flesh gills, and scales to ensure freshness. The eyes should be clear, plump, wet, and shiny. The tail and dorsal fins should be fresh, wet, and intact. The flesh should feel firm and should spring back when pressed. The gills should have a bright color, not slimy or have a dark brown or dark color. Finally, the scales must be moist, shiny, and firm. Your nose is also helpful for checking fish; fish should have a mild scent, not a strong fishy smell.
